When I try to go to gmail.com to open my gmail account, I am directed to a page asking me to set up a Google account. Previously i could type gmail.com and it would take me to my gmail inbox. Has something changed?

Thanks for the response. It has probably been two months since I accessed the gmail account since I have an AOL account. When I go to sign in, I am directed to a Google screen asking me to set up a new Google account. When I enter my gmail ID, it tells me that ID is already established.
